- \VINIDING TEEOHANISM.

Application filed March 25, 1926'. Serial No. 97,471.

This invention relates to a mechanism for winding libre reed or other similar material. upon spools or reels. It is one object of our invention to provide a winding mechanism by which a plurality of reeds delivered simultaneously to a winding machine in different parallel paths may. be accurately guided to separate spools or reels.

A further object is to provide driving means by which each spool or reel may be rotated independently of each other spool or reel and at ust the required speed to take up the reed or other material delivered thereto.

Our invention further relates to improved r guiding devices for delivering the reed to the spools, and to other arrangements and combinations of parts which will he hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings in which- Fig. 1 is a plan view of a part of a folding and winding machine embody our invention;

Fig. 2 is a sectional elevation of one of the winding reels;

Fig. 3 is a sectional plan view, taken along the line 3-3 in Fig. 2;

Fig. 4t is a partial end elevation of certain driving mechanism for the winding reels, taken along the line 4c":t in Fig. 1;

Fig. 5 is an enlarged elevation of the traverse feed of the winding mechanism; and

Fig. 6 is a detail perspective view oi the free end of one oi the guide arms.

o have shown our improved winding mechanism as embodied in a. machine tor making fibre reed, which product is preteraloly manufactured by tolding a. strip of heavy tough paper or tibre longitudinally to a three-ply thickness, pressing the folded fibre to size the reed and to break down the tibre at the told lines. then unfolding the fibre, gumming the unfolded strips, allowing the gum to partially dry and become very sticky, and thereafter refolding and repressing the fibre.

In Fig. 1, we have indicated the fibre strips S approaching the refolding rolls 111 and 112 and being delivered from suitable presser rolls in a series of parallel paths.

I .As the stripst i leave the refolding and re pressing mechanism, they are delivered to the winding mechanism shown generally in Fig. 1 and shown in detail in Figs. 2 to 5.

The winding mechanism is especially designed to receive a plurality of finished fibre reeds from a set of refolding and repressing devices and to wind each reed upon a separate spool or reel. For this purpose, we have provided a winding table 140 having bear lugs 111 (Fig. 2) for a plurality of vertical winding shafts 142. corresponding in numher to the number of refolding and repressing devices.

The shafts 142 are provided at their lower ends with hovel gears 14:3 meshing with corresponding bevel gears 1414 on a liOriZOntal driving shaft 145 supported in bearings below the table 140. The shaft 1 15 may be continuously rotated from any suitable and convenient source of power.

A disc 146 (Fig. 2) is secured to each vertical shaft 142 and rotates therewith in a re cess 1 17 in the top of the table. A driving ring l-ftS rests loosely upon the upper face 01" the disc 1&6 or may be separated therefrom by a disc 149 of leather or other friction material. The ring 148 is provided with a driving pin 150 adapted to engage one of the cross arms 151 of a winding reel or spool 152. Each spool 152 is provided with bushings 153 fitting loosely on its winding sha it 142. A In actual operation, the winding shafts 14-2 are continuously rotated at a speed suflicient to wind up the reed as delivered from the refolding meeluinism, even when the read is being wound upon the smallest diameter of the spool. in fact. the speed of the shatt 142 is usually slightly in excess of the requirementis for winding at the smallest diametcr.

Each separate reel or spool 152 is thus yieldingly rotated at the exact speed required to wind up the reed as it is deliver d thereto. The excess speed of the shaft 142 is taken care of by the slip bet ween the. driving disc 1 16 and the driving ring 14-8.

Each spool is thus driven independently of every other spool and at such speed as will take care of all oi the reed delivered to that particular spool. As soon as one spool is tilted. it. may he removed and replaced by ill) an empty spool without interfering with the operation of any of the other spools which may be only partially tilled.

We have also provided a traverse mechanism for laying the reed upon the spools, this mechanism comprising a traverse bar having a plurality of guides secured thereon and also having a plurality of guide arms 157 pivoted thereto.

The guides 156 and guide arms 157 are.

mounted on the bar 155 or on brackets or plates 158 secured to the bar 155 and projecting at one side or the other from the bar and to different distances, so as to bring the guides 156 in alignment with the corresponding refolding and repressing devices and so as to pivot the guide arms at points closely adjacent to their associated guides 156.

Each guide arm 157- isformed at its free swinging end substantially as indicated in Fig. 6, being provided with an inverted U shaped guiding loop 159, open at one lower edge as indicated at 160 for conven ent threading of the reed. A. lug 161 retains the threaded reed in position and prevents unthreading thereof.

The traverse bar 155 is mounted upon upright supports 162 one of which is shown in Fig. 5. The supports 162 are slidable in fixed bearings163, and each support 162 is provided with a rack bar 164: engaged by a pinion 165 mounted on a traverse shaft 166. The shaft 166 is rotatable in fixed bearings 167 (Fig. 1) and is provided at one end with mangle pinion shaft 170 atits swinging end has a limited sliding movement in a bearing 175, permitting the pinion to engage the pins 176 (Fig. 4t) of the mangle gear, either on,

the inside or the outside thereof, as is usual in such mechanism. The end of the shaft 170 is preferably received in a cam groove 177 (Fig. t) which passes from the inside to the outside of the row of pins 176 at a particular point in the circumference of the mangle gear 168.

Continued rotation of the mangle pinion shaft 170 thus causes alternate movement of the mangle gear shaft 166. first in one direction and then in the opposite direction and such movement is effective through the pinions 165 and rack bars 164- to raise and lower the traverse bar 155.

Reference to Fig. 1 will show that the length of the guide arms 15'? as well as the position of the pivots therefor is varied in accordance with the lateral position of the pivots necessitated by the difFerent align.-

ments of the reeds delivered from the repressing mechanism.

' d e have thus provided a winding mechanism particularly adapted for use in conjunction with a n'iachine for making fibre reed and we have provided a machine in whichv each strip of reed will be taken up by its respective winding spool regardless of the size of the spool or the speed of rotation of any other spool in the machine. We have also provided guiding means by which the strips of reed delivered in different parallel paths may each be accurately guided and directed to the corresponding winding spool and we have provided a suitable traverse mechanism by which the reed will be placed on the spools in uniform and suitably disposed layers.

Our. improved winding machine is also particularly advantageous from the fact that the spools are merely slipped loosely on and oil of the winding spindles and that the operator need give no attention whatever to making a driving connection between the spool and the spindle.

Having thus described our invention and the advantages thereof, we do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims,but what we claim is1- 1. In a winding machine, a spool, means to rotate said spool, a traverse bar, a guide on said bar, and a guide arm pivoted adjacent said guide and having its free swinging end positioned adjacent the winding surface of said spool.

2. In a winding machine, a spool, means to rotate said spool, a traverse bar, a guide on said bar, and a guide arm pivoted adjacent said guide and having its free swinging end positioned adjacent the winding surface of said spool, said free arm end having an inverted U-shape guiding loop and having an opposed abutment eifective to retain a strip of material in said loop.

3. In a winding machine, a plurality of winning shafts, spools loosely mounted thereon and freely rotated thereby, means to deliver a plurality of strips of material in spaced paths extending substantially parallel to the center line of said winding shafts but at different (listances therefrom, a traverse bar, means to reciprocate said bar adjacent said spools, a guide for each strip on said bar'. said guides being variously spaced from the center line of said shafts and each being substantially aligned with the path of one of said strips.
